The European Commission publishes an FAQs document on UDI System

GS1 06 Sep 2019

The EC has published a Frequently Asked Questions (FAQs) on changes in the legislation with regards to Unique Device Identification (UDI) System under the EU Medical device Regulations 2017/745 and 2017/746.


These new Regulations (Regulation (EU) 745/2017 on medical devices and Regulation (EU) 746/2017 on In Vitro diagnostic medical devices) introduce an EU identification system for medical devices based on a Unique Device Identifier (UDI).


The UDI system will:

• facilitate easier traceability of medical devices

• significantly enhance the effectiveness of the post-market safety-related activities for devices

• allow for better monitoring by competent authorities

• help reduce medical errors and fight against falsified devices

• improve purchasing and waste disposal policies and stock-management by health institutions and other economic operators


The New Rules 

Any manufacturer shall assign a unique UDI to a device and to all higher levels of packaging before placing that device on the market except custom-made medical devices and performance study/ investigational devices. 

The UDI carrier shall be placed on the label of the device and on all higher levels of packaging and in case of reusable devices on the device itself (direct marking).
